Heat shrinkable teflon tubes and sleeves
Supply and application of heat-shrinkable fluoroplastic (teflon) tubes and sleeves.
Basic information
BALTRO is a provider and applicator of heat shrinkable fluoroplastic (often simplified to "teflon") tubes and sleeves, made of PTFE, FEP and PFA materials (types of fluoroplastics).
These are provided in standard dimensions (diameter from 2 mm up to 800 mm and length from 600 mm up to 11.000 mm) but also specially customized to satisfy particular, specific requirements.

Use
These products are being used primarily in the area of measurement and control technology, medicine, textile, chemical, automotive and food industry, in the field of electroplating, as well as in the aerospace industry.
Due to the number of surface treatments for rollers, we have prepared a summary of 5 ways how you can protect your rollers on our blog.
Application
Using a special technology, heat shrinkable tubes and sleeves get enlarged in diameter, so that the application can be done; by subsequent warmig, they shrink back almost to their original dimension.
The most common shrink ratios are 2:1 or 4:1 for PTFE and 1.3:1 or 1.6:1 for FEP and PFA materials. Please contact us with a specific shrink ratio demand. Fluoroplasts, and PTFE in particular, require special know-how for application on components. Based on a previous consultation, we will suggest a specific solution.
Two-ply heat shrinkable tubing, so-called "DUAL", is a special product that combines two types of fluoroplastics. The outer cover is made of PTFE while FEP is the inner material - which, after melting, serves as a fixation to the workpiece surface.
The recommended shrink temperature in °C (approximate figures)
Shrink temperature may vary according to the lot and must be determined (specified) in advance - during the test procedure.
| PTFE | FEP | PFA | DUAL | |
|---|---|---|---|---|
| Shrinking temperature | 330 | 190 | 220 | 330 |
| Melting point | - | 275 | 310 | 275 |
| Operating temperature (continual) | 260 | 205 | 260 | 205 |
